CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 426,219, dated April 22, 1890.

Application filed July 5, 1888. Serial No.2'79,141. (No model.)

.To all whom it may concern.-

Be it known that we, JOsEPH C. SIMMONS and TVILLIAM I-I. TURNER, citizens of the United States, both residing at Martinsville, in the county of Clinton and State of Ohio, have invented a new and improved Check- Row Attachment for Corn-Planters, of which the following is a full, clear, and exact description.

The object of this invention is to provide a drill, stepdrop, or check-row attachment, preferably the last, which maybe used in connection with most any of the ordinary forms of planter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of a portion of a planter, representing the same as provided with our check-row attachment. Fig. 2 is a detailed view in perspective of our check-row attachment.

In constructing such an attachment as the one illustrated in the drawings above referred to we provide a clutch-collar secured on. the main shaft 19 by means of a set-screw, a wheel 2 containing at one side of the hub a clutch member and at the other a ratchetwheel (it is preferred. that both of these wheels be parts of wheel 2;) a spring 6, coiled about the main shaft 19; alever 5, containing a pawl 20 and an eyebolt 21, through which is made to pass the curved or sector-shaped guide 18, which guide is attached at its extremities to the frame-work of the machine; a wheel 2, containing lugs 22, which may be used in such numbers and placed in such positions in the elongated slots 23 as maybe desired; an arm 3, which works on a pivot 24 which pivot is attached on the framework of the machine, one extremity of the arm 3 coming in contact with lugs 22, and at the other extremity is attached a scoop or blade 25; a spring 1, connecting the arm 3 with the framework of the planter; aplate 10, which may be conveniently attached to most planters. This plate 10 contains two guides 20, a post 11, carrying a spring 16, and a lever 17, V'shaped at one extremity and containing a slot at the other. A sliding plate 8 is mounted upon the plate 10, where it is held in position by the guides 20. The sliding plate 8 contains projections 7 and 28, post 12, bolt 13 carrying the spring 15, and bolt 14 carrying the bar 16. A spiral spring 16, carried by two posts 11 and 12, is also provided As the planter is moved forward, the main shaft 19 causes the clutch-collar 1 to rotate. By means of a coupling the wheel 2 is made to rotate accordingly. The coiled spring 6 causes the aforesaid couplingtoremain joined. The said coupling may be joined or disjoined at pleasure by means of the lever 5; also, by means of the lever 5 the wheel 2 may be turned forward or reversed, as may be desired. As the wheel 2 rotates, the lugs 22 come in contact with the arm 3, causing the scoop 25 to make a mark in the earth. The spiral spring 4 holds the arm in an elevated position when not depressed by the lugs 22. The lugs 22 also come in contact with the projection 7, serving thereby to actuate the slide 8, which is moved intermittently in a forward direction against the tension of the spring 16. lVhen this occurs, the pivoted bar or pawl 16, at the front end of the slide 8, will engage the V-shaped rear end of the lever 17, vibrating the latter and causing a reeiprocatory lateral movement to be imparted to the seed-slide 29, which is connected with the lever 17 by means of a pin 30 passing through the slot at the front end of said lever.

In operating this machine the distances at which the grain is to be deposited are regulated by the number and position of the lugs 22 in the wheel 2. e are enabled to checlm'ow the grain properly by the manipulation of the lever 5, which permits us to accelerate or retard the deposit of grain at pleasure, and correctly in reference to the marks made at regular distancesin the earth by the scoop 25.

Having thus fully described our invention, we claim as new, and desire to secure by Letters Patent= 1.. In a checlvrow attachment for cornplanters, the base-plate adapted to the frame of the machine and h avin g longitudinal guides or flanges, in combination with the slide, a pawl mounted upon a vertical pivot on said slide, a spring engaging said pawl to hold it in operative position, a lever pivoted upon the basaplate, its front end connected with the ICO seed-slide and its rear end havinga V-shaped projection, and a tappet-Wheel adapted to en gage a projection at the rear end of the slide to intermittingly actuate said slide, substantially as set forth.

2. The combination of a lever adapted to be connected with the seed-slide and having a V-shaped rear end, a slide having a pawl to engage and actuate said lever, a retractingspring for said slide, a wheel having adj ustable tappets to actuate said slide, a ratchet- Wheel, and a clutch member on opposite ends of the hub of said wheel, a segmental guide,

' a lever mounted loosely in the latter and engaging an annular groove in the hub of the Wheel, and a pawl pivoted onsaid lever and engaging the ratchet-Wheel 011 the hub of the tappet-wheel, substantially as set forth.

3. The combination of the marking-lever carrying the shovel or marker, the spring to hold the rear .end of said lever normally raised, the lever connected with the seedslide and having V-shaped rear end, the slide having a pawl to engage and actuate said lever, a retracting-spring for said slide, a tappet-wheel to engage and actuate said slide and the marking-lever, and a lever having a pawl engaging a ratchet-Wheel on the hub of said tappet-Wheel, said lever being loosely mounted on a curved support or guide and engaging the hub of the tappet-Wheel, which may be moved laterally on its shaft into or out of engagement With a clutch on said shaft, substantially as set forth.
